Allelopathic hypotheses revisited: the interactions between native and exotic species in the Brazilian savanna [PDF]
We investigated allelopathic interactions between native and exotic species of the Cerrado biome. We studied the effects of the exotic Andropogon gayanus and the native A. bicornis on the initial growth of two native (A. fastigiatus and Lepidaploa aurea)

Insecticidal activity of a Melinis minutiflora grass extract on Stomoxys calcitrans flies
Several extraction methods were utilized to study the insecticidal activity of a Melinis minutiflora grass extract. Four concentrations (10, 20, 40, 80%) of the product which had the highest yield (i.e., a wax-free hexane extract) were tested to establish its insecticidal activity on S. calcitrans flies (adults and larvae).

Insights on the Potential of Natural Regeneration to Restore Cerrado Open Ecosystems
The colonisation potential of native Cerrado species in degraded areas will depend on the remaining underground structures and not on seed rain from nearby conserved remnants. Effective restoration of the Cerrado will not be possible without active restoration, if the bud‐bank are not present in the system.

Burn them all? Use and efficacy of fire as a tool for grassland restoration
Grassland ecosystems have suffered significant degradation and restoring them is fundamental to fight against climate change and biodiversity loss. Fire is an important component in the evolution and management of grasslands worldwide and can potentially be used to restore grasslands. In this paper, we present a systematic literature review to know how

Abstract The invasive exotic plant Melinis minutiflora P.Beauv. is a globally invasive species and impacts the economy, biodiversity, and human well-being. The challenges of biological invasion may be intensified by climate change. The increase in temperatures and concentrations of greenhouse gases may favor the introduction, establishment, and

ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).
